Will be adding pics of the pattern as I go along with the changes I make....
not going to comment on the pic of the driveshaft in your hand...
You doing these by trial and error and running patterns? Because this will be the result
pinion depth gauge, back lash gauge and setup bearings are your friend.
Measure, do math, insert shims, slide setup bearing on, re-measure, do more math, add or subtract shims. Once you like your math, run a pattern. remove setup bearings, press new bearings on, do final install. Generally only need to run 1 pattern if your math is on.
Hopefully you have a bearing puller or press and not trying to use a punch and hammer to remove and install your bearings constantly. Thats a recipe for fucking something up.
I'm sure you have a good game plan though.
